Solvent Vacuum Distillation

[@Polymershik]

For the first time I see distillation with no condenser in assembly. Just a tubes with vaccuum outlet between evaporating and receiving flask! :)

[@dumbeau]

Great video! I'm doing polymer research where the syntheses are ridiculously sensitive to impurities and I needed to salvage my crude monomer because buying more would take too long (I procrastinated). Thank you for saving me an awkward meeting.

[@SeriousPigi]

"this video is not a substitute for proper lab training", meanwhile in many labs they just say go and figure it out

[@firstmkb]

Thanks for posting. You explained it very well.

[@karlm5022]

LOVE THE CHANNEL! Would be so cool if you could do a freeze dry a acetone solution into the liquid Nitrogen cold trap! I'm pulling my hair out trying to figure out how to keep the solution in a frozen state while I pump

[@jonhoyles714]

love the chemistry videos keep them coming great stuff :)

[@Snizzfart]

It seems as though no one in the comments knows what a vacuum transfer. We essentially do the same process when drying C6D6 for our glove boxs (except we use NaK).

[@muhammadfaheem4319]

u have made easiest process to the difficult one

[@colosistvan]

You are the cutest and prettiest scientist I have ever seen so far ;)

[@nop58653]

Fuck**g SIMP! 😂 jkjk bro

[@MichaelLapore-lk9jz]

Could you also put argon into the system?

[@rogierodjokarijo4712]

Yes. Argon is the better choice but nitrogen is less expensive

[@frankdavisiii9514]

Yes but where I am argon is almost 7 times more expensive than nitrogen. A 270L liquid tank of nitrogen costs ~70$ and the same size argon tank costs ~480$

[@andikusnadi1979]

On meniute 4 30 what liquid it pour to container?

[@danielstjean9458]

Does it matter if you don't flush the side arm of your solvent bomb with nitrogen before applying vaccume to the receiver?

[@jhyland87]

What brand of glassware are you using?

[@saisivakumar522]

There is no condensor before the receiver flask.

[@MistakenMystery]

You don't need one, the room temperature is cold enough to make it condense

[@no0channel0at0all]

Why is there no cold trap to protect the vac pump

[@michaelpayne4408]

there is, pause at 10:19 you can see it on the left with the blue diamond-patterned sleeve

[@EumEhChuh]

What is the black and white stopper called?

[@srjones64]

Just to be clear, this is pretty crude level of materials handling. The evacuation times shown here are very short, there is not the usual 3 fold pump-flush cycling with inert gas, typical of Schlenk manipulations. This might be sufficient for simple syntheses but not for use with highly air sensitive compounds.

[@michaelpayne4408]

well, except she did do three cycles 3:10, just didn't include it in the video. Watch the whole thing so you can give credit where it's due

[@billgates9417]

Can you show us the operation of the vacuum cold trap ?

[@JamBear]

+Bill Gates The Schlenk line, you mean?

[@raju9950500]

sir, what is use in chemical distillation second flask coldness use.? without condenser ? please reply me.

[@Seorful]

Hi, she's using liquid nitrogen to cool the receiving flask.

[@MrRoboskippy]

Cool! Do 90% hydrogen peroxide next!

[@MrRoboskippy]

I'm not sure how a vacuum still works. I'm guessing a pump sucks the air out. If so, how do you not lose the h2o2. If the water evaporated under vacuum and left the good stuff, then no problem. Do you put some kind of chiller in there to condense the peroxide or what?

[@Blu702]

You people are dumb, distilling concentrated hydrogen peroxide is dangerous. Every video ive seen they're worried about it exploding.

[@jordanandrews6479]

Very helpful, thanks

[@TheSonicmook]

The sound quality is'nt very good, which means that one can't hear what you are saying clearly. (Drying over calcium what? 18 seconds) A transcript might have been useful in this case. Otherwise it looked liked it might have been very informative.

[@sandokannoname5738]

+sonic mook But is very good!!!! And it is for free as well....you ned some more?? Abetter lab? bufff, sometimes I dream..... and I can see myself at work in a similar one........doesn´t matter they will improvove it for you ( I dont´t lknow why but in my dream I have 8 arms like an octopus, but better you know,because I also ......Yes!!!! 8 hand Do you want the chemist to be fired?...but she is a beautifull lady, a good chemist and is very nice looking her polite way in the performance of the experiment.

[@dumbeau]

The drying agent was calcium hydride, if you care. You can use other drying agents like anhydrous magnesium sulfate or calcium chloride depending on your solution too.

[@sorkeror]

Cool, I've never heard about vacuum destillation before I saw a bottle of whisky from a Swedish distillery where they actually use it

[@ClownWhisper]

this would be a great way to distill ammonia hydroxide into stainless

[@theghostofsw6276]

Boy...there's a lot to keep in mind, when you're doing this.

[@bigrockets]

your fan on the hood is almost overpowering your voice

[@uncleserge2598]

Nice glasses

[@kpedretty3012]

We told you multiple times... stop using the MS vial dish for water baths

[@momsmushroomsjodyfoster5786]

I think smart people are very attractive 😊

[@nop58653]

SIMP!

[@marcellevieira3124]

TKS!

[@alschuck3061]

i love you and you brain

[@nop58653]

Fuck**g SIMP!

[@hamishferguson4166]

pretty lass!

[@nop58653]

Fuck**g SIMP! 😂

[@wucash5672]

Cute voice and accent :D I got drunk and broke lots of my glassware and set 1/2 my house on fire inhaled a heap of mercury vapor. Follow this girl not me.

[@nop58653]

SIMP! 😂

[@ClownWhisper]

clamp the lab jacks

[@momsmushroomsjodyfoster5786]

I was a scientist in my first life😂

[@boilshifter1350]

I'm not in yet 10sen. and the only thing I can think of is how incredibly cute you look

[@georgebernacchi1532]

Too dangerous the way she does this. Nitrogen??? Why. Chiller or ice water.

[@abhikshitmandal3330]

😀👍

[@trupak85]

hot girl with liquid nitrogen is my weakness

[@nop58653]

Fuck**g SIMP! 😂

[@pragatiswain6914]

please distill the noise around you first..

[@5eZa]

Cute

[@nop58653]

Fuck**g SIMP!😂

[@4pharaoh]

Please consider adding captions or wearing a microphone. I'm sure you wanted to be helpful, but the high background noise made your video unusable. Sorry.

[@ltchance]

Yeah, first not indian chemister)

[@meltdownproductions5148]

.

[@VitalySarychev]

Explanation is not very good. It can be more complex. Sound is not exellent. Noise, pauses in speaking..

[@bigrockets]

your fume hood is making so much racket I can hardly understand you.

[@leeknoz935]

I didn't learn anything only have more question

[@raju9950500]

sir, what is use in chemical distillation second flask coldness use.? without condenser ? please reply me.

[@dumbeau]

Instead of using a condenser, she set the receiving flask in liquid nitrogen (-196° C boiling point so you know it's cold).
